as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to conveyers, and particularly to a system of excavating and filling cyanid or other vats or receptacles;

and some of the objects of this invention are to provide a system of this general character wlnch'wi'll be comparative] simple in construction,while being rapi and efficient in operation. 7

Another object of the invention is to provide means for rapidly fillingand emptying bins, vats, or other receptacles and to distribute the material supplied to-the bin or vat evenly throughout the entire area there- 7 of and which can be operated to gradually feed the contents of the bin or vat to a central discharge-o ening.

It is also an object of this invention to provide means for discharging and distributing the material within the vat or receptacle in a uniform manner in-a finely-divided state by centrifugal action.

A further object of the invention is to provide means for filling and emptying, as well as distributing, the material operated upon in a plurality of tiers of vats or receptacles and also to provide such means constructed to be transported from one tier of vats or rece tacles to another.

ith these and other objects in view the invention consists, essentially, in the construction, combination, and arrangement of parts, substantially as more fully described 1n the following specification, and as illustrated in the accoin anying drawings, formingpart of this appl1cat1on, in which-- gure 1 is a sectional view through a tier of vats or rece tacles, showing the operative mechanism in e evation, partl broken awa Fig. 2 is a side elevationa view, art y broken away, taken at right angles to Fig. 1. Fig. 3 is an enlarged perspective view of the actuating mechanism, and Fig. 4 is a detail of construction. a a

Slmllar characters of reference designate views;

Referring to the drawings, "the reference character 1 designates a trestle-work or fram mg supporting vats ,or receptacles -2, here rarefied March 27, ieoe.

corresponding parts throughout the several shown as arranged in twotiers; but any number of tiers may be employed and any number'of tiers can be arranged 1n a line in order that the means for filling and emptying the vats or receptacles, as well as distri uting the material therein, may be moved from one tier of vats or receptacles to another, as

hereinafter more fully explained. Arranged on each side of the tiers o vats or receptacles are timbers 3, supporting track rails 4, whereon travel wheels 5, on which is mount- I ed a frame or platform 6, supporting inclined braces 7, connected with uprights 8, attached to cross-pieces 9, and constituting a central vertical frame 11, rovided with suitable braces, all whereof orms a traveling structure or bridge which may be of any desired construction and formation arranged to support the actuating mechanism substantial y as shown. Beneath the lower vats is preferably disposed an endless conveyor 10, constructed to receive the treated material from each of the lower vats and ,to conveythe same to theplace of de osit or for further treatment,'as will be rea ily understood- Suitably mountedin the vertical frame 11, so as to permit of vertical movement, is a shaft 1 12, having a plurality of arms 13, carrying depending brackets or hangers 14, revolubly' supporting concavo-convex disks or other devices 15, preferably arranged "at such an angle in relation to the arms 13 as to progress or turn over the material within the vats or re ceptacles 1 toward the central discharge-o ening therein, which opening is designate by thereference character 16 in the upper-vats or receptacles and 17 in the lower vats, the latter openin being preferably closed bya a hinged or siding door 18 or in any other suitable manner.

, The upper tanks or rece tacles are preferably provided with a doub e bottom 19, having a central opening registerin with the opening 16, and a ring or other preferably secured between the bottom of the upper tank around the opening 16 therein, and said ring 20 is preferably provided with hooks or other devices21 to receive eyes upon one end of the clam ing-rods 22,

passing through openings in t e flange 23 evice 20 is 24, Fig. 4, resting on the bottom 19 of each of the upper tanks around the opening 16 in the bottom of such tank, substantially as illustrated in Figs. '1 and 4 of the drawings. ,5 By means of this construction the shaft 12 may be extended and operated through the upper tank and act upon the'material in the lower tanks whenever it is desired to do so and when this operation is effected the loops or eyes 25 upon the upper set of arms 13 are engaged by the hooks 26 upon the frame 'or -platform 6, Fig. 1, as subsequently ex-,

plained. The lower set of arms 13 are also preferably provided with loo s or eyes 25,

15 constructed to be engaged by ooks 26 upon a truck or carriage'27, supported upon wheels 28, traveling upon tracks or ways 29, desirably dependmg and supported from the frame or trestle work whereon the u per vats are supported, substantially as ustrated in Figs. 1 and 2 of the drawings.

The shaft 12 is preferably provided with a recessed collar '30, carrying arms 13 and having bolts tapped therein to enter threaded 2 5 openings in the enlarged end or head 31 of said shaft when it is desired to operate upon 'the material in the upper'tanks, t being understood that the sleeve 24 and rods 22 will then have been removed substantially as 0 shown in Fi' 2, andthevarms 13 will then be rotated by t e action of the shaft 12, so that the disks 15, carried by the upper set of arms,

, will progress or turn over the material in the upper tank toward the center thereof, where- 3 5 by it will drop through the opening 16-upon the centrifugal distributer 32, which will evenly and uniformly distribute the material over the bottom of the lower tank or receptacle, as hereinafter more fully explained.

The centrifugal distributer 32 embodies a vertical shaft 33, carrying radial arms 34,

n preferably of different length, and the shaft is preferably provided with a bevel-pinion 35, driven by a beveled wheel 36 upon the 5 drive-shaft 37, which may be actuated in any suitable manner, (not shown) and the centrifugal distributer 32 is preferably mounted .on a carriage or truck 38, having wheels 39,

constructed to travel on the tracks 29, before referred to, and a hopper or chute 40 may be mounted in or upon said truck to direct the material upon the distributer. By means of this construction thecentrifugal distributer may be moved along beneath each of the vats or receptacles and discharge the material from the upper vat into the vat below in an even and-uniform manner, while subjecting the material so distributed to the'action of v the air, so essential in treating certain classes of material. When thecentrifugal distributer is used, it is forced along upon its tracks .29 under the vat to be emptied; but when the lowerset of arms 13 are to be usedthe centrifugal distributer is moved away a nd a removable shaft-section 41 is lowered by means of the Windlass or drum 86 and is connected with the head 31 of the shaft 12 and with said arms by means of tap ed bolts, and said shaft-section is guided an steadied in a two-part bearing 42, secured between jaws 43 upon brackets or hangers 44, mounted beneath the upper tank or upon the framing 1, sup orting the same, substantially as illustrate In this manner the shafts 12 and 41 are guided and steadied, and the lower set of arms 13 can be readily operated within the lower tank or receptacle for the purpose of progressing) or turning over the material which has en uniformly discharged therein by the centrifugal distributer toward the central discharge-openim 17 in the lower tank, from which the material falls into a hopper or chute 40, which directs the same upon an:

endless or other conveyer '10, for transportation to the place of deposit or further treatment.

The mechanism for actuating the operative parts before described preferably consist in the shaft 12, splined or feathered to a lar e bevel-wheel 46, Fi s. 1 and 3, and upon t e shaft 12 is mounte a cross-head 47, workin in guides or ways in the vertical frame 11 and havin threaded connection with one or more threa ed rods 48, mounted in said frame and carrying gear-wheels 49, meshing with a gearwheel 50 won a rod 51, also mounted in said frame and carrying a beveled pinion 52,

meshing with a beveled gear-wheel 53 upon the shaft 54, and with said beveled gearwheel 53 meshes a beveled pinion 55 upon the shaft 56, carrying a large gear-wheel 57 and a ratchet-wheel 58, engaged by a ratchet device 59, connected with a ink 60, attached adjustably to a crank 61 upon the driven shaft 62, carrying a loose gear-wheel 63 and a beveled pinion 64, meshing with the large beveled gear-wheel 46 on the shaft 12, whlle a clutch 90, operated by a clutch-lever 91, throws said wheel 63 into and out of engagement with the driven shaft 62 substantia ly as particularly illustrated in Fig. 3 of the drawings. A shaft 65 may also be mounted in the vertical frame 11 parallel with the shaft 56 and ma be provided with a pinion 66, meshing with the gear-wheel 57 on said shaft, and loose and fast ulleys 67 may also be mounted on the shat 65, which has a crank or handle 68 to rotate the same, and belts 69 pass over one or other of the pulleys 67 on the shaft 65 and .over one or other of the pulleys 70 on the driving-shaft 71, having a pmion 72, meshing with the large gear--- wheel 63 on'the shaft 62, and on the drivingshaft 71 are fast and loose pulleys 72, connected by a belt 73 with fast and loose pulleys upon the propellin -shaft 74, carrying a pinion 75 at each end t ereof, meshing wlth gear-wheels 76 upon the shafts of the trackwheels 5, supporting the traveling structure or bridge before described; but, if desired,

awl or cent loose pu eys by means of a sliding rod 80 flexibly connected with the long arm 81 of a bell-cranklever 8-2, the short arm 83 where-- of contacts with or rests upon the cross-head I 1 547 and is elevated by the' u'pward movement jof the latter to shift the belt 69 when the shaft 5 threaded rods 48, rotating in the cross-head 12" is elevated by the action or rotation of the 47 and actuated by the wheels 49 and 50, the

f beveled inion 52, the beveledgear-wheels 53,.beve pinion 55, shaft 56, ratchet-wheel 58 thereon, links 60, gear-wheel 63, and pinion7 2 on the driving-shaft 71, substantially as shown. By means of thisconstruction the 4 the drawings.

shaft 12 is automaticall elevated or depressed through the medlation of the parts 311st described, or said shaft can be raised or lowered by hand when the belt 69 is on the loose pulleys 67 and 7Q by turning the crank 68, thereby rotating the pinion 66 thereon, which in turn rotates the gear-wheel with the result before attained automatically.

The removable shaft-section 41 may be sup orted, lowered, and raised from the vertica frame 11 by means of a rope or cable 84, passing up over a sheave and being connected with a drum 86, wound by means of a crank 87 ,essentially as illustrated in Fig. 3 of The operation of this invention will be readily understood from the foregoing description when taken in connection with the accom-' panying drawings and the following explanation thereof. If it is desired to move the material from the upper vat to the lower empty vat or receptacle, the sleeve 24 will be removed by means of the ro e 84.and drum 86, and-the centrifugal distri uter 32 will be forced along u on the tracks 29 until it is directly below the discharge-openings 16 and will then be put in motion through its driving-shaft 37, while the shaft 12 will be rotated by the gear wheel 46, pinion 64, driven shaft 62, carrying the loose gear-wheel 63, rotated (when the clutch men aged therewith) by the pinion 72 on the riving-shaft 71, substantially as before explained. The" rotation of the shaft 12 carries with it the arms '13, which have been previously disengaged from the hooks 26 upon the platform 6 i of the traveling structure or bridgeand have been lowered upon and bolted to the enlarge-i ment or head 31 of the shaft 12 in the manner shown'in Fig. 2 of the drawings, whereb ,the rotation of the arms 13 causes the dis s 15 carried thereby to progress or turn over the material within the upper tank toward the material falls into .thechute or hopper 40 upon the traveling carriage or truck 38 and is thereby directed upon the centrifu'al distributor 32, actuated by its drivin -s aft'37 and pinions 36 and 35, substantiifily as beuniformly and evenly distributed upon and over the bottom of thelower tank or receptacle and is at the same time subjected to the 9 "tion f' the air in a finely-divided state. Afterthe upper vat or receptacle shall have been .'-thus emptied of its contents'thecentrifugal distributer will then be moved from under the discharge opening 16, and the shaft 12 will be elevated in the manner before deper set of arms 13, which are then supported upon the hook or other devices 26, as 1n Fig.

sition and the shaft 12 is a ain lowered, and the shaft-section 41 is also owered by means of the drum and ro e 84 and is attached to the head 31 ofthe shaft 12, aswell as to the lower set of arms 13, which are at that time sup orted from their carriage or truck, Fig. 2, t at has before been moved'under thedis charge-opening 16 of the upper vat in order to permit the connection or attachment of the shaft-section 41 with said lower set of arms, as will be readily understood, whereupon the shaft 12 is rotated as before and the the materialin the ower vat-or receptacle toward the discharge opening 17 therein, through which opening the material falls into the endless conveyer 10 therebelow, which transports the material to the place of final and-lower tanks, as described.

It is not desired to li- 't or confine this invats in each tier, as any number of rows may beem loycd, as well as any number of vats -with the particular excavating.arms or disks shown and described or to the articular dis tributer disclosed';here in, and ifferent forms of actuating mechanism may be employed, if found desirable in practice.
